This is a 2012 Pierce Velocity PUC. I built this in 6 wide, adding details such as the Federal q siren on the bumper, red and yellow stripes on the bumper and rear, and the Fire Research light above the front windscreen.

Nice work. I hate chevrons but awesome job making them out of Lego and no decals! Only thing I would change would be the hosebed. It's to high and it doesn't look like a hosebed. Add some gray panels to split it up. Other than that great work.
